UNIVERSAL AND AUTOMATIC TIP F013, GAS-BURNERS.

Specification of Letters Patent.

Patented May 16, 11916.

Application filed August 3, 1915. Serial No. 43,417.

To all whom it may concern:

Be it known that I, FRANK L. GILMAN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Universal and Automatic Tips for Gas-Burners, of which the following is a specification.

My invention relates to improvements in universal and automatic tips for gas burners, operating automatically by placing or removing a cooking utensil; and the objects of my improvements are; first, to provide a tip with a .joint attachable to any gas-cock or valve, having a lining of soft material, as lead, babbitt, cement, or the like, to be attached to different sizes and kinds of cocks with different threads, or without threads; second, to provide a recess inside of the open end of the tip, having a hole for pouring a soft material into the recess when fitting the tip to a cock; third, to provide a small valve at the farther end of the tip, an extension of which projects through a bore in the closed end of the tip; and, fourth, to provide means for operating the small ,valve, automatically by placing a cooking utensil over the burner or removing the utensil.

The invention consists in the combination, construction and arrangement of devices hereafter more fully described and claimed, and illustrated in the accompanying drawing, in which- Figure 1- is my device attached to a burner; Fig. 2 is a vertical longitudinal section of my device. Fig. 3 is an end view of my device.

The grate 1, burner 2, gas supply tube 3, and cock 4, see Fig. 1, constitute the part of a gas range, hot plate, or gas stove, to which my tip is attached.

In Fig. 2 is the end 5 of the cock 4 shown, having the open end 6 of my tip surrounding it. Upon the inside of the open end 6 a recess 7 is shown, having an opening 8 provided for pouring a soft material as lead, babbitt, cement, or the like, around the end 5 of the cock 4, whereby my tip is rigidly and tightly connected to the end 5 of the cock 4. It will easily be understood that a lining of soft metal can be provided inside of my tip to make it attachable to cocks and valves of gas-burners when no such soft material is on hand of the user. In such cases, the soft metal will be poured in at the factory, by using a piece of steel lnstead of the cook, the steel will be chosen of smaller diameter to allow a fitting of the soft metal-lining to different sizes of cocks, thus forming a universal connection. At

the farther end 9 of my tip is a bore 10,

15, see Fig. 8, which serve as bearings for my operating lever 16. The end 17 of the operating lever 16 extending toward my tip is bent to fit in the operating rod 18, which is of flat metal to take little room, but at the same time to be strong enough to operate the small valve 12, to the end of which it is attached. The other end 19 of the operating lever 16, (see Fig. 1) is extending upwardly above the grate of the gas stove. A cooking utensil placed over the burner will press the lever 19 down, thereby turning the operating lever 16 in the lugs 15, and the end 17 swings toward the cock 4, which direction is followed by the operating rod 18, thereby opening the small valve 1.2, and gas can escape to the burner through the cut 14, and bore 13, shown in Fig. 2. To close the valve 12, a spring 20 is placed around the operating lever 16, between the lugs 15, (see Fig. 3) one end of the spring being attached to lever 16, while the other end of the spring is resting against the lug 15. Removing the cooking utensil from the burner, the end 19 will be released and the spring 20 will turn the operating lever 16, thereby swinging the end 17 away from the cock 4, which in turn closes the valve 12.

A pilot burner 21 is attached to the body member of my tip, (see Fig. 1.) This makes my tip a complete construction; gas stop, operating means, and pilot burner being all formed by, or attached to my tip, which can be attached to any cock of a gas burner with my universal connection as described.

Having thus described my invention, I claim:

1. A tip for the purpose described, consisting of a body member being hollow at one end and having in the farther end a bore which forms a valve seat, a valve having a disk like part normally to engage with the valve seat and" a cylindrical part forming the guide for the valve the cylindrical part being provided with a bore and a out just below the disk part adapted to allow gas to pass out of the valve, and means adapted to automatically operate the valve.

2. A tip for the purpose described, consisting of a body member being hollow at one end and having in the farther end a bore which forms a valve seat, a valve having a disk like part normally to engage with the valve seat and a cylindrical part forming the guide for the valve, the cylindrical part being provided with a bore and a out just below the disk part adapted to allow gas to pass out of the valve, a pilot burner attachedto the body member of the tip, and operating means adapted to automatically operate the valve.

3. A tip for the purpose described, con- I sisting of a body member being hollow at one end and having in the farther end a bore which forms a valve-seat, a valve having a disk like partnormally to engage with the valve seat. and. a cylindrical part forming the guide for the valve, the cylindrical part being provided with a bore and a out just below the disk part adapted to allow gas topassout of the valve, a pilotburner attached to the body-member of the tip, the hollowend of the body-member being provided with a recess and a hole from the recess outwardly designed to be filled with a soft metal adapted to form a universal connecting means for my tip,- and Contact thin patent may: be obtained for five cents each, by addressingth'e;Commissioner of.
